The Area of a Triangle Based on Two Angles and the Interior Side calculator computes the area of a triangle given the measurement of two of the triangle’s angles and the dimension of the interior side.
INSTRUCTIONS: Choose units and enter the following: :
Area of a Triangle (A): The calculator computes the area of the triangle in square meters (m2). However, this can be automatically converted to other area units (e.g. square feet) via the pull-down menu.
The formula for the area of a triangle based on two angles and the length of the side in between them is:
`A = (c^2 * sin(β) * sin(α)) / (2 * sin( 2π - α - β)`
